Which of the following is an example of an auxiliary station?
A station sending one-way transmissions between a remote repeater receiver and the main repeater transmitter✓الإجابة الصحيحة
A backup radio for emergency use in case the main station radio fails
A station used in the Military Auxiliary Radio System for linking government and amateur stations in a digital network
A second station utilized in multi-operator contest stations
الشرح
An auxiliary station carries point-to-point traffic inside a system of cooperating amateur stations, which is exactly what a link from a remote repeater receiver to the repeater transmitter does. A spare radio, a MARS link and a second contest position are ordinary stations, not auxiliary ones.
